The difficult decision too humanely euthanize Mullaya was made yesterday,January 8,2026,after a period of declining health. This event serves as a poignant reminder of the delicate balance of animal care and the importance of recognizing when compassion dictates letting go.
Understanding Mullaya’s Journey and Health Decline
Throughout the past year, Mullaya experienced a consistent loss of weight, despite intensive supplemental feeding with specialized formulas and eucalyptus puree.

However, as the rate of weight loss accelerated in recent weeks, accompanied by increasing weakness and a diminishing appetite, a deeper investigation became necessary.
To alleviate his suffering, we made the compassionate choice to euthanize him.
